UV LED sterilization lamp bead, as a cutting-edge technology in the field of sterilization, has been widely recognized and applied in various industries. This article will provide an in-depth introduction to UV LED sterilization lamp bead, covering its definition, working principle, application fields, advantages, and future development trends.

Definition of UV LED Sterilization Lamp Bead

UV LED sterilization lamp bead refers to a semiconductor light-emitting diode (LED) that emits ultraviolet (UV) light in the wavelength range of 200-400nm. The main material of the LED is usually gallium nitride (GaN), which has excellent photoelectric properties. Compared with traditional UV lamps, UV LED sterilization lamp bead has a smaller size, lower energy consumption, and longer service life.

Working Principle of UV LED Sterilization Lamp Bead

The working principle of UV LED sterilization lamp bead is based on the photoelectric effect. When the forward bias voltage is applied to the LED, electrons and holes in the semiconductor material are separated, and when they recombine, ultraviolet light is emitted. The wavelength of the emitted light is determined by the bandgap of the semiconductor material. In the case of UV LED sterilization lamp bead, the emitted light mainly includes UVC (200-280nm), UVB (280-320nm), and UVA (320-400nm) wavelengths, among which UVC has the strongest sterilization effect.
